Leukemia

Leukemia is cancer of the bone marrow, the spongy substance inside bones where blood cells are produced. In this condition, cancerous blood cells are produced in the bone marrow and are then transported into the arteries that supply blood to rest of the body. These cells may infiltrate the liver, spleen and lymph nodes. Leukemia is classified based on the type of cell involved and the stage of maturity of the leukemic cells.
